Gunong with missing pommel

[Sajen]

Hello friends,

have won recently this gunong with missing pommel. When I received it there was a surprise, all fittings seems to be from silver. And the construction of the handle is very unusual in my opinion. On the tang is a piece of horn attached with a hole in up. I suppose that the missing pommel was attached with a pin through the pommel and this horn piece. do you agree? I plan to restore the gunong so all comments are very appreciated. The gunong is very heavy and has a laminated blade of a somewhat unusual form. I think to remember that Jose once write that gunong with silver fittings are from Sulu. Remember I correct?

Thanks in advance,

Detlef
